BREAD-RAISER.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed September 2, 1905. Serial No. 276,822.

To aZL whom it may concern:

Be it known that I, CnARLEs H. MARSHALL, a citizen of the United States,residing at Brockwayville, county of Jefferson, State of Pennsylvania,have invented a new and useful Bread-Raiser, of which the following is aspecification.

In the operation of raising bread as ordinarily carried out it is quitedesirable that the bread be maintained at a uniform temperature inexcess of that of the surrounding atmosphere. This is difIicult ofaccomplishment with the means ordinarily at hand. I provide aconstruction of bread or dough raiser to fill this want which isinexpensive, capable of being readily cleaned, requires comparativelylittle space, and protects the dough from dirt and undesirable moisturewhile it is being raised.

A further purpose of my invention. is to guide the outer and inner pansto their proper relative positions by means upon the lid.

A further purpose of my invention is to provide for keeping the mass ofdough being raised at a uniform temperature throughout.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, Figure 1 is a vertical section of mybread-raiser through the center thereof. Fig. 2 isa fragmentaryperspective of a portion of the lid and closure for an opening therein.

1 designates a pan, can, or other compartment capable of holding hotwater or other liquid, which is provided with a lid, cover, or top 2,knotted. at 3. The lid is retained in place by snaps, clips, or catches4 engaging with the edge thereof, said snaps being fastened to the sidesof the pan at 5. Handles 6 are located in proximity to the snaps andpreferably over the same in order that these handles may guard the snapsfrom accidental disengagement and may limit movement of said snapswithin the range of recovery of thematerial used.

Within the outer pan I provide a receptacle 7, forming an inner pan,preferably placed centrally thereof and. preferably havi ng its sidesconforming in general shape to the shape of the outer pan. I have shownthe pan and bread-receptacle as both tapered in shape and of circulareross-section--that is, circular truncated cones; but it will be evidentthat my invention does not depend Upon the bottom of the receptacle 7 Iform a support 8,

which I have shown as of screen form and which is attached to the innerpan in order that it may afford a firm support all around the pan with aminimum of material and may not require any placing of support orinitial centering of the pan.

Within the top 2 and preferably centrally thereof I form a dependingflange 11 of sufficient depth to engage with and form a fairly tightcover for the receptacle 7, which is for this purpose preferably flaredat the top thereof, while the flange is correspondingly preferablytapered, as shown. Near the rim of the top or lid and upon the same sidethere of as the flange 11 I form a corresponding tapered flange 12,fitting within the preferably-flared top of the outer pan. Thiscombination of tapered flanges upon a common lid is advantageous fromthe standpoints both of simplicity and utility. The flanges guide thetwo pans into their concentric or other predetermined relative positionswithout necessity of care in the inltial placin of the parts and providea close fit of the li to the inner pan without sticking of the parts,such as occurs in a close fit between cylindrical parts.

I may provide an opening in the lid 2 between the receptacle 7 and theouter pan 1 for admission of water, covering the opening in any desiredmanner, as by the reverselybent slide in Fig. 2, whose oppositeapproximately parallel sides 13 14 embrace the edges of the slot 15 andwhich after insertion is kept straight therein by the downturned. clipsor projections 16, which with the part 17 intermediate the sides 13 and14. act as guides. A knob 18 makes ready movement possible and at thesame time unites the sides at this point and keeps them sprung againstthe lid from opposite sides thereof. An ordinary hinged lid mightevidently be used. for a closure of this opening.

In assembling my bread-raiser I place the receptacle 7 containing thedough to be raised within the can 1 and fill the space between the panand receptacle with warm water or other liquid. to a height preferablyat least equal to the height of the dough in the receptacle. I thenplace the lid upon the pans, centering them thereby and. coincidentallycovering them from impurity and preventing the moisture from the hotwater from coming in contact with the dough. At intervals, if necessaryto maintain the dough within the permissible range of temperature, hotwater ITO may be added to the water already Within the pan 1. Thetemperature may also evidently be maintained at any desired point bykeeping the pans in a Warm room free from cold drafts.

It Will be evident that various changes may be made by those skilled inthe art Which Will come Within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a breadraiser, a plurality of concentric pans and a cover commonto said pans having tapered flanges thereon centering and closing all ofsaid pans.

2. In a bread-raiser, a plurality of pans arranged one Within anotherand separated from each other at the bottom and sides, a lid common toall of said pans, clips for said lid secured at one end to the outer panand handles for the outer pan, restraining eX- cessive movement of theclips.

" 3. In a bread-raiser, an outer pan, an infor the outer pan embracingthe clip and restricting its movement.
